Between the spindle 9 and record roll 11 is a stationary female die 18 containing apertures 22 disposed in vertical alignment with the key levers, and above said die is a guide bar 19 to which said die 18 is secured, as, for instance, by screws 20. A narrow space or slit is left between the guide bar 19 and die 18 through which space the record may pass. Connected to each key lever 13 and to the arm of the space bar 14 is a punch or male die 21 which extends down through a hole in the guide bar 19 and is adapted to enter one of the apertures 22 in the die 18. The punch may be in the form of a round rod which cooperates with the round apertures 22 in the die in punching out the perforations in the record. The dies are disposed crosswise of the record and are spaced apart so as to correspond with the locations of the slots in the tracker bar of the pneumatic instrument in which the record is used. record 10 passes under and over tension bars 10 and 10 interposed between the roll 9 and the die 18. Said tension rods are supported by the end frame members of the machine.

The connection between the key levers and punch may assume any desired form, and, as shown in the drawings, the upper end of each punch 21 is made in the form of a spherical head 23 connected to the body portion of the punch by a neck, the head being confined in a socket in the key lever conforming generally to the shape of the head and neck, as is clearly illustrated in Fig. 2. It will be understood that the perforations in the record are made by depressing the key levers and space bar. After each perforation has been made, the record must be advanced one step, and the mechanism for so advancing the record will now be described.

Upon one end of the winding roll 11 is a ratchet wheel 24, and below said ratchet wheel is a lever 25 pivoted at one end to the side frame member 6 and having secured to it a pawl 26 which is arranged to engage with the teeth of the ratchet wheel 24. A spring 27 connected to the pawl and to the lever 25 serves to yieldingly hold the pawl in engagement with the ratchet wheel. A spring actuated detent 28 pivotally mounted upon the side frame member 6 engages with the ratchet wheel 24 and prevents retrograde movement thereof.

A solenoid or other electromagnetic device 29 is supported by the end frame member 6 above the free end of the lever 25, and the core 30 of the solenoid is connected to the lever by a pin 31. A coiled compression spring 32 confined between the solenoid 29 and lever 25 serves to depress the end of the lever connected to the core, and a lug or other stop member 33 is provided on the frame member 6 to limit the downward movement The of the lever. It will be observed that whenand rotating the ratchet wheel and therewith 7.

the winding roll 11 and advancing the record 10 one step.

, Means controlled by the key levers and space bar and by the-solenoid are provided for making and breaking the circuit through the solenoid whenever a key lever or the space bar is released after having been depressed to form a perforation in the record. The electric control means will now be described.

Below the key levers and arms of the space bar is a transversely extending bar 34 which is arranged to be depressed by each lever and the arms of the space bar whenever those members are depressed, and said bar 34 actuates the contact making and breaking mem bers. Pivotally mounted on the side frame member 6 is a contact lever 35, one end of which is connected to the bar 35 by a link or rod 36 having a lost motion connection with the contact lever A contact member 37, carried by one end of the lever 35, is arranged to be brought into contact with a stationary contact member 88 carried by a bracket 39 and secured to the side frame member 6.

A spring actuated detent 40 secured to the side frame member 6 engages with the lever 35 and serves to hold the same in the two positions occupied by it, namely, the position wherein the contact pieces 37 and 38 make contact with each other and the one wherein they are separated. As shown, one end of the lever 35 is formed with a pointed or tapered end 41 against which the detent 4O bears, the arrangement being such that the peak at the pointed end of the lever passes the engaging part of the detent when moved from one to the other of its operative positions. The detent acts by reason of its pressing engagement with the inclined edges of the end portion of the lever to hold it in either of its said two positions.

On the contact lever 35 is a lug or other shoulder 85 which is arranged to be struck by the lever 25 whenever the latter is moved upwardly by the solenoid. When the shouldered end of the contact lever 35 is moved upwardly, the contact piece 37 is moved down thereby breaking the circuit for the solenoid through the contact pieces 37 and B8. The shoulder 35 may have an adjustment screw threaded therein for affording adjustment between the lovers 25 and 35.

The contact piece 37 is electrically conpiece 44 by an-electricconductor 45, the ends: of which are secured to the bracket 39 and tOw the bracket 46 in which the stationary con tact piece 44 is mountecb A second movable contact piece 47 co-operates with the stationary contact piece 44 in closing the circuit through the contact pieces 37 and 38 and the a solenoid, and said movable contact piece 47 isactuated'by the bar 34. a

-, As shown, the bar 34 comprises part a rectangular rocking frame 48 pivotally mounted upon the side frame members 6 and-1 6 The frame 48 may comprise the bar 34, a bar 49, parallel therewith, and end'bars 50. Pins or stud shafts 51 mounted in the V. side frame members affordthe pivotal coni 47 is secured on one end of the end bar 50 in tact piece 44.

nection between the frame 48 and said side frame members. The movable COHtEIClZ'PIGCG position to contact with the stationary con: A spring 52 connecting the rocking frame 48 with the side frame meming frame in raised position underneath the her 6 serves to hold the bar 34 of said lockkey levers and also serves to hold the movable contact piece 47 in contact with the stationary contact piece 44, except when a key lever or space bar is depressed. In normal position of the bar 34, the contact piece 37 is held out ofcontact with the contact piece 38, whereby the circuit through the solenoid remains broken so long as all of the-key levers remain in their normal-position.

An electric conductor 53leads from a bindmg post on theaend bar and an electrlc K conductor 54. leads from the solenoid.,and said electric conductors 53 and 54 may lead to any suitable sourceof electric supply. It will be understood that the contact lever 35 and rocking frame 38 are insulated from each other and from the brackets 39 and 46 and that the circuit through the solenoid is closed onlywhen both movable contact pieces 38 and 47 are in contact with the stationary contact pieces 37 and 44. A lever fulcrumed on the side frame member 6is provided for manually-actuating the pawl26 in case it is desired to advancethe recordindependently of the roll advancing mechanism.

In the operation of the machine, the end of, the unperforated record carried by the roll 9 is passed between the tension rods 10 and 10 and through the slit between the die 18 and bar 19 and is secured to the winding roll 11. .Therecord is perforated by depressing the key levers and space bar in the ordinary V manner of operating a typewriter. Each time a key lever or the space bar is, depressed, the punch or. male. die 21 punches a perforation in the record.

hen a key lcver is depressed, the bar 34 of the rocking frame 48 is swung downward andtherewith one end of the contact lever 35 isdepressechwhile the end contaming the movable contact piece 37 .is swung upwardly,

.;thereby brifnging; Said. movable, contact piece into'contact with the;stationarycontact piece 38. The detent 40, by-reason of its engagementwith the lever35, holds; said lever in the position so occupied by it vwith the contact pieces 37 and 38 incontact, although the bar 34 and link 35 are moved upward when the key lever is released.

The downward movement of-the bar 34, caused bythe downward movement of the 'keylever, results in an upward movement of the part ofv therocking frame 48-which car rice the movable contact member 47, and, consequently, the contact pieces 44 and 47 are held out of contact so. long as the bar 34 re mains depressed. It will be seen, therefore,

which being energized, draws up the long arm of the lever 25 and advances or rotates the ratchet wheel 24 one-step through the en- 9 gagement ofthe pawl 26 therewith. Consequently, the record is. advanced one step upon the roll 11.

As the lever 25 moves upwardly it encounters the shoulder 35 onthe contact lever 35, thereby swinging upwardly the end of the lever 35 which is connected to the link 36, and swinging down its other end, consequently separating the contact pieces 37 and 38 and breaking the circuit through the solenoid. It will be seen, therefore, that the closing of the circuit through the solenoid is timed to take place whenever a key lever is released after having been depressed, and that the circuit is broken the instant that the roll 11 has been advanced one step.

The two circuit closing members for the electric circuit of the solenoid operate in reverse order, so that normally the circuit is open at one of said places and remains open at one orthe other of said places at the raised or depressed position of any of the key levers,

eXcept at the instant a key lever returns to its raised position after having been depressed. The act-ion of said circuit closing members in breakin the circuit at one place and closing it at another and vice versa may be regarded as reversely acting in the following claims.
